Esperamos seguir ofreciéndote una buena experiencia. ### 5/5 — 跟随系统显示模式来日夜间模式就更好了！ *2026-09-28* 已经购买，支持👍好用！ **Developer response:** 谢谢啦，这个需求已安排！！ ### 5/5 — 好用，售后给力，五星推荐。 *2026-09-24* Ui很好看，开发者审美在线，软件功能非常实用。之前购买后出现一些问题，开发者果断处理，点赞👍。 **Developer response:** 感谢您的认可与好评🥰！很高兴 UI 和功能可以得到您的喜欢。遇到问题我们都会尽力快速处理，如果后续使用中遇到任何疑问，欢迎随时联系我们，祝您使用愉快✨ ### 5/5 — It is important to keep track of the timing for suspended matter. *2026-09-23* Please support the display of a countdown timer in the floating window. **Developer response:** Thanks for your kind review! Your request for countdown timer on floating window has been recorded. We will evaluate this feature for future releases. ### 4/5 — 灵动岛显示费电 *2026-09-22* 灵动岛显示功能主要是解锁使用时观看，但是开启后锁屏也会显示，这样每天电量耗费很高，关闭后解锁又不显示。 **Developer response:** 非常理解您担心耗电的问题！目前 iOS 系统机制限制，灵动岛实时活动和锁屏实时活动是绑定开关，无法分开设置，开启后锁屏也会展示内容，但**实际耗电量很低**；如果关闭，解锁后的灵动岛就不会显示了。我们也期待后续系统能支持分开控制，实在抱歉给您带来困扰。 ### 1/5 — 充电功率 不准 *2026-09-21* 界面设计没什么好说的 可以给一星但是充电测试一点不准 和硬件测出来的功率相差很大 **Developer response:** 非常抱歉给您带来不好的体验，也很感谢您愿意把问题反馈给我们。 关于充电功率检测和硬件实测存在差异这一点，我们非常重视。如果您方便的话，可以通过 APP 内的 "我的 - 意见反馈 " 入口把您的使用情况和实测数据发给我们，这能帮助我们更好地核实、优化充电功率检测功能。 ### 5/5 — It's a very practical app. *2026-09-21* The features are fairly comprehensive—it basically pulls out all the sensor data from the iPhone. The only thing missing is cellular info, which still isn’t available—keep up the good work. The pricing is reasonable, I guess. For people who find it useful, the price isn’t too high. ### 5/5 — 功能清晰，数据丰富 *2026-09-19* 很不错的一款软件 **Developer response:** 非常感谢您的支持！很高兴我们的软件能帮到您。我们会继续打磨细节、丰富数据，期待未来能给您带来更多惊喜！ ## Frequently asked questions about Device Kit ### What is Device Kit?
